analogWrite(redPin, leds[(k + 120) % 360]); // Set 120deg relative phase for red LED analogWrite(greenPin, leds[k % 360]); // No phase shift for green analogWrite ...

If you have the led with common anode or negitive terminal, connect it on the 'gnd' on Arduino ('gnd' is the negitive terminal in an Arduino). If you have the led with the common cathode or postive ...

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Being able to use one of your old projects to make a new one better can be quite satisfying. [Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network ...

the RGB LED color mixer is a project that is suitable for the beginner Arduino users who is interested in building an interactive gadget to mix colors. The simple circuit combines three potentiometers ...

Infineon's RGB LED Lighting Shield is one two of Arduino-based evaluation boards created to showcase the capabilities of its ARM-based XMC1000 MCUs in lighting and motor control applications. Unlike ...

The real-life closeup image of a WS2812B LED is given below. You can see that the WS2812B die is connected to 3 individual LEDs namely Red, Green and Blue using gold wires. The video below shows the ...

Among quantitative analysis techniques, molecular absorption methods in the ultraviolet/visible region are the most commonly employed in chemical laboratories worldwide. In general, the absorbance ...
